The present invention relates to a hydrophilized membrane which has greatly suppressed adhesion of blood cells such as erythrocytes, leukocytes and blood platelets within blood, by easily conducting hydrophilization of a hydrophobic porous membrane, and a process for the hydrophilization. The present invention relates to a hydrophilized hydrophobic porous membrane which is obtained by impregnating a medical supply of which the part which comes into contact with blood is hydrophobic in a solution of a substance having surface activity, then rinsing in a solvent into which the surfactant is soluble, and adsorbing an extremely small amount of the substance having surface activity to the surface of the part which comes into contact with blood, wherein the adhesion of blood cells such as erythrocytes, leukocytes and blood platelets within blood is greatly suppressed. The present invention also relates to a process for hydrophilization.
摘要:
The aggregation and phase separation of inorganic particles are performed in a sol containing the inorganic particles and a solvent to produce a porous body having open pores. Preferably, the inorganic particles are particles of one or more inorganic material selected from the group consisting of titania, silica, alumina, zinc oxide and zirconia. Further, the sol may have strong acidity and the pH of the sol is elevated to perform the aggregation and phase separation of the inorganic particles. Alternatively, the sol may have strong basicity and the pH of the sol is lowered to perform the aggregation and phase separation of the inorganic particles. The present invention provides a novel method of producing a porous body and sintered body having co-continuous structure, applicable to a wide variety of inorganic materials.

A masking pattern is performed on a substrate by using materials that are weakly adhered to the substrate, and then the masked substrate is etched. Since the mask is weakly adhered to the substrate, the mask is peeled off from the surface of the substrate, so that a gap is generated between the mask and the substrate, and then anisotropic etching is performed. According to this method, it is possible to easily manufacture an optical measurement substrate having recesses whose sectional shape can be approximated to a curve having inflection points. Therefore, optical characteristics of a minute amount of substances can be evaluated efficiently without the loss of incident and reflected light even when measuring light is incident at an angle of less than 45 degrees.

An apparatus and method are provided to perform an insulation-displacement connecting operation and a cover mounting operation efficiently, and hence to improve a yield for insulation-displacement joint connectors having many contacts. The apparatus includes a press unit (200) with a slide unit (220) for carrying connection-assisting parts, such as a wire-checking device for checking a housing of an insulation-displacement joint connector, a wire pushing device and a cover holder. A wire checking operation, a wire pushing operation and a cover mounting operation are performed continuously by switching the slide unit (220) by means of a switching device (230) and successively driving the connection-assisting parts by means of one press (210).

A transfer film capable of transferring thin films such as a conducting film, a heat absorption film onto a display apparatus panel, a method for fabricating thin films for a display apparatus panel using the transfer film, and a display apparatus having thin films fabricated by the method are provided. The transfer film is constructed by forming a conducting film layer and an adhesion layer on a base film. The transfer film is disposed on the display apparatus, and a heat pressure adhesive bonding process is performed to transfer the conducting film layer to the display apparatus. A high quality display apparatus is realized by fabricating a high quality conducting film using the transferring process.

A process for producing refined methacrylic acid comprising the steps of oxidizing methacrolein and the like catalytically in a vapor phase to form a methacrylic acid-containing gas, cooling and condensing the gas to an aqueous methacrylic acid solution, adding to the solution an organic solvent that forms two liquid phases with water to carry out an extraction operation and thereby to obtain an extract, bringing the extract into contact with water to mix them together, separating the mixture into an organic phase and a water phase, and distilling the organic phase. According to this process, highly refined methacrylic acid containing little dibasic acids such as maleic acid and citraconic acid can be obtained economically and without increasing wastes that are unrecoverable to the process.
